The effects of parton energy loss and p perpendicular to-broadening in cold nuclear matter on the pi and centrality dependence, at various rapidities, of J/psi suppression in p-A collisions are investigated. Calculations are systematically compared to ES66 and PHENIX measurements. The very good agreement between the data and the theoretical expectations further supports pi-broadening and the associated El:tedium-induced parton energy loss as dominant effects in J/psi,, suppression in high-energ,p-A collisions. Predictions for J/psi,, (and Upsilon) suppression in p-Pb collisions at the LHC are given.
